<P>PROBLEM TO BE SOLVED: To provide a gravure printing machine and a method of exchanging the plate cylinder of the gravure printing machine, capable of improving productivity and economical efficiency by shortening the exchange time of the plate cylinder. <P>SOLUTION: In the printing machine 1, a print unit 2 includes a drive side support shaft 21, a driven side support shaft 25, a phase detection means 28, and a phase adjusting means 27 which is controlled by a control part for the printing machine and rotates the driven side support shaft 25. When exchanging the plate cylinder 20, the control part for the printing machine controls the phase adjusting means 27 to match the phase of a newly attached plate cylinder 20, supported by the drive side support shaft 21 and the driven side support shaft 25, to a prescribed phase for register on the basis of inputted phase detection signals. <P>COPYRIGHT: (C)2013,JPO&INPIT |
